How to prepare a public bid in Latin America

Public procurement in Latin America runs on national electronic systems, and each country has its own law, portal and vocabulary. A bid prepared for Colombia cannot simply be translated and sent to Peru. What carries over is a method: find the notice early, translate the rules into a checklist, fix the paperwork that takes weeks, and keep a written record of every question.

Know the portal before you know the market

Every country has a central portal where tenders are published, and many make registration free. The ones you will meet most often are these.

• Colombia. SECOP II, run by the national procurement agency, Colombia Compra Eficiente. Suppliers register in the supplier directory, and the first user for a company creates the supplier account with its legal name, tax ID and legal representative details.
• Chile. Mercado Publico, run by ChileCompra. About 850 state institutions procure under Law 19,886, and all their bids go through the platform.
• Peru. SEACE, the electronic system administered by the OECE under Directive N 007-2025-OECE-CD. Operators on the public-entity side hold a personal, non-transferable certificate. A new general public procurement law entered into force on 22 April 2025, so older guides need checking.
• Ecuador. The SERCOP portal and its official procurement system, which also feed the open data published by the agency.
• Brazil. The PNCP, described by the federal government as the official site for centralised and mandatory publication of the acts required by Law 14.133/2021, the general law on tenders and contracts for the Union, states, Federal District and municipalities.
• Mexico. The federal government's procurement platform is ComprasMX, and rules differ across federal, state and municipal levels.

Do not rely on a single portal for a sector you want to enter. Multilateral bank projects, state-owned enterprises, municipalities and regional governments often publish elsewhere, and some state companies sit outside the central procurement law altogether. The Open Contracting Partnership notes, for Colombia, that some procedures and certain state companies that compete with the private sector are excluded. Chile's data likewise leaves out public companies.

Foreign suppliers: what Colombia's guide says

Colombia's procurement agency publishes a guide for foreign suppliers that shows the type of questions you should ask in any country. A foreign company may be represented by a legal representative or an attorney, and the person who signs the offer must be able to show authority through a power of attorney or an appointment, together with an identity document. A foreign legal entity does not have to set up a branch to submit an offer. It must do so if it wins a contract that requires a constant presence in Colombia, such as works, services or a concession.

The Colombian single register of bidders, the RUP, is not required for foreign suppliers without a domicile in the country. They prove the same information directly to the contracting entity, as the bidding documents specify. For legal capacity, the entity asks for documents that prove existence and composition under the home-country law, such as a certificate of good standing, the articles or the partnership contract. For experience, it accepts certificates from third parties or copies of contracts. For financial capacity, it asks for audited financial statements from the previous year, with the data needed to convert foreign-currency figures. The guide sends readers to Circular Externa N 17 of 2015 for the rules on apostille, legalisation and foreign-language documents.

The lesson is general. Foreign suppliers usually need three things in hand early: corporate documents legalised for use abroad, certified experience, and audited accounts that someone has converted into the local currency. Each can take weeks.

Build a compliance matrix

When the bidding documents arrive, read them with a spreadsheet open. List every requirement, who in your team owns it, the document that proves it and the date it is due. Divide requirements into three classes. Admissibility requirements decide whether your bid is read at all, and include signatures, bonds, forms and legal documents. Qualification requirements measure your capacity, such as experience, financial ratios and key staff. Scoring criteria rank the bids that pass.

Most bids lost on technicalities fail on admissibility. A missing signature, an expired certificate or a bond written in the wrong form can end a good bid. Give one person the job of checking the final package against the matrix, and let that person be someone who did not prepare any section.

Plan backwards from the deadline

Mark the deadline, then work back. The final package must be ready at least a day before submission to leave room for portal problems. Certificates and legalised documents come first, because they depend on third parties. Translation, notarisation and apostille can each take days. The bid bond depends on a bank, and in several systems it must be issued by a locally recognised bank or insurer, so contact your bank early. Financial statements follow the local calendar, and in Colombia the guide notes that if the audit is not finished by the fifth business day of April, a signed statement and a pre-audit report may be accepted.

Leave the technical and price proposal for the last stage only if the design work is done. Pricing reflects taxes, social charges, the exchange rate, inflation and payment terms. Foreign firms most often misprice by missing local taxes on imported items, local labour charges and the time the entity takes to pay.

Use the clarification window

Public tenders have a period in which bidders can ask questions, and the answers are published to all. Ask about anything that is ambiguous, contradictory or restricts competition, and ask in writing, with a reference to the clause. Questions also reveal what competitors are worried about, because the published answers are visible to everyone. If a requirement looks designed for one supplier, say so politely in a question and keep the record. Many systems let bidders challenge the tender documents before the deadline, and that window closes quickly.

Partners and local presence

Entities score experience, and a foreign company without regional references starts behind. A local partner with certified experience can fill the gap, either in a joint venture or consortium or as a subcontractor, depending on what the documents allow. Check the rules on joint liability, the minimum stake of the member that holds the experience, and whether the same firm may appear in more than one bid. A separate guide on this site covers joint ventures.

After the award

Keep reading. The contract usually requires a performance guarantee, a local branch or representative if the work needs presence, registration with the tax authority, insurance and local hiring or content commitments. Payment terms and the track record of the entity matter as much as the price you won at. Before you sign, ask whether the entity pays on time, in what currency and by what mechanism, and what recourse you have if it does not.

Public tenders are public, so you can learn from past ones. Open datasets covering past awards in Ecuador, Colombia and Chile let you see who won, how much they were paid and how often the entity used each procedure. Our guide to open contracting data explains how to use them.
